Several other countries have joined the U.S. and Europe to launch and maintain Earth observation satellites, building on the legacy of the USGS Landsat program and aided by a 2008 policy shift that allowed no-cost worldwide access to the long-serving orbiter\u2019s data archive. Commercial players have expanded their footprint, launching small satellites by the hundreds. The diversified field of remote sensing now leans heavily on broadband Internet access, cloud computing, high-performance computing, and machine learning to maximize the impact of Earth observations.<\/p>\n

In short, more people than ever have access to and use satellite data. What hasn\u2019t changed is the USGS commitment to ensuring global leadership, engaging with users, making useful and reliable data readily available, and ensuring continuity in land remote sensing observations.<\/p>\n

Recognizing the field\u2019s growth and shifts in focus, the USGS National Land Imaging (NLI) Program recently asked the Landsat Advisory Group (LAG), a subcommittee of the National Geospatial Advisory Committee (NGAC), to review the 1992 Land Remote Sensing Policy Act and provide guidance for discussions on its future.<\/p>\n

The final LAG report on the almost 30-year-old statute was reviewed and approved during the April 2021 LAG meeting, and is available online at this link<\/a>.<\/p>\n

\u201cRevisiting the Land Remote Sensing Policy Act of 1992\u201d delves into changes to the field and the Landsat program\u2019s successes over the past 30 years, and outlines \u201ca modernized interpretation of the Act in a manner that remains consistent with the spirit of the existing language.\u201d It notes that the Act\u2019s goal to encourage the use of Landsat data for research and applications has largely been realized.<\/p>\n

\u201cOne of the things that was surprising to me going into this, given how much has changed in the 30 years since this was written, was how much of (the Act) was still relevant, and how much the key objectives that were laid out in it still apply,\u201d said Dr. Mariel Borowitz of Georgia Tech, a LAG member and one of the report\u2019s co-authors. \u201cThe changes were really about \u2018how do you achieve those objectives in the current context?\u2019\u201d<\/p>\n

LAG Leans on Diverse Experience, Expertise<\/p>\n

The LAG is a standing subcommittee of the NGAC, whose members are appointed to 3-year terms by the Secretary of Interior. The NGAC includes members from Federal and State agencies, academia and commercial groups, while the LAG includes both NGAC members and members with specific areas of remote sensing expertise.<\/p>\n

\u201cThe NGAC is a phenomenal group, and the Department of Interior works hard to foster diversity in every possible way,\u201d said co-author Keith Masback of Plum Run LLC, a former NGAC and current LAG member. \u201cThat\u2019s helpful not just in that it brings together people with these complementary backgrounds and perspectives, but also because those members can go back to their respective communities and share the good word from the NGAC, so to speak.\u201d<\/p>\n

Images taken from Landsat 8, including this one taken in January of 2020, is just one of the many federal sources of geographic data in the United States.<\/p>\n

Masback, for his part, brought decades of remote sensing experience from a national security perspective to the table when work on the report began two years ago. Borowitz, meanwhile, brought an international policy perspective. Before joining the LAG, Borowitz authored the book \u201cOpen Space: The Global Effort for Open Access to Environmental Satellite Data,\u201d which delved into the global impact of the 2008 Landsat Free and Open Data Policy. \u00a0<\/p>\n

\u201cLandsat is one of the most important examples of transitions in data policies and the effect they can have, especially the move to an open data policy,\u201d Borowitz said.<\/p>\n

Multiple studies have calculated the economic benefits of the 2008 open data policy to be in the billions of U.S. dollars. The policy has also expanded the remote sensing community, with tens of thousands of active Landsat users now spread across academic institutions, private businesses, Federal agencies, State and local governments, and nonprofit organizations.<\/p>\n

Between 1986 and 1992, for example, an average of 400 peer-reviewed publications cited Landsat in their titles, abstracts or keywords each year. By 2017\u2014after the implementation of the open data policy\u2014that figure had jumped to 1,200.<\/p>\n

About 5,000 Landsat images were distributed each year before 2008. Today, the Landsat program distributes millions of images each year.<\/p>\n

The open data policy led the way for other programs, notably the European Space Agency\u2019s Copernicus Sentinel-2 missions, to provide open access to Earth observation data. The LAG reviewed and re-affirmed the open data policy in mid-2019<\/a>. The open data policy also served to support the rapidly-expanding commercial remote sensing industry\u2014another of the LRS Act\u2019s stated objectives.<\/p>\n

\u201cUsers may experiment with relatively low-resolution Landsat data before turning to commercial providers for more precise imagery,\u201d the report said. \u201cCommercial entities use Landsat data to calibrate their own instruments and sometimes offer products that fuse their commercial data with free government data.\u201d<\/p>\n

Report to Guide Discussions on Future Policy<\/p>\n

The report\u2019s conclusions on the Act are not prescriptive, and they weren\u2019t meant to be. Instead, the authors framed their discussion points in the form of questions.<\/p>\n

\u201cThe idea here was to create a document around which these discussions can circle,\u201d Masback said. \u201cWe\u2019ve taken a hard look at this, tried to boil it down to something consumable, and those questions can be relevant to a variety of fora.\u201d<\/p>\n

How should the Landsat program approach and accomplish data continuity, for example? In the interest of meeting the Act\u2019s broad goals, should the Landsat program expand its objectives beyond medium resolution land imaging to include the collection of water and atmospheric data? What role does Landsat play in global leadership as other Nations expand their satellite programs, and how can or should the Landsat program leverage partnerships with programs like Copernicus? And finally, what principles for a new national land remote sensing policy would best serve to inform and maintain global leadership for the U.S.?<\/p>\n

\u201cCertainly, these are the types of questions the Landsat Advisory Group would be looking at, and that\u2019s one potential way forward,\u201d Borowitz said. \u201cBut I think you\u2019ll see these debated in other venues, as well. In the broader policy community, these questions are really relevant.\u201d<\/p>\n
